My advice is to make sure how much electricity you have. It would be important not to overbuy on gear. i would advice on electricity run 240 to save cables, also it's much nicer to have all that power there if you need it.
Also ventelation you will need to find some way to cool it down. With winter for a lot it will help a lot. But be aware cooling down the mining area most likely is needed.
Sage advice. I over bought equipment on my first mine and was shocked at the heat output of just 10kW.
There is a lot to be said for doing it in smaller batches. Do X amount run it for a at least a few day's to week then order more. Repeat until your happy with number, or you can't handle more.
Going from 0 to a lot is just a major undertaking. Only reason to do it is if your ordering so much you got a discount (most do not fit into this). My summer it was a lot of trial/error. I had to much and kept adding things to help with air flow till I was good. Would have been much easier on myself to do smaller a few times.
It was much harder to maintaining the air flow when we were using GPUs to mine bitcoins. Good old days.
I disagree or it might be I just went bigger with asics... although I was decent size on GPU's. GPU's I had a lot of little fans, and AC in some rooms (yes AC I was new and using it to).
Then go to summer mining with ASICs now I was using lots of CFM's of fans. Had to buy a industrial exhust. upgraded some vents to help air leave. I consider my area a "hobby" not "home" miner. I do still put one like I did with Avalon 6 in house right now so I can relate to home mining. But having a area for just miners is much nicer.
Sadly a big nice fan died... even though it's winter I went and got another one and am going to try warranty on other. Hopefully I have a extra after they fix it (I hope) the store could have cared less on the year warranty after 3 months you go to manufacturer according to them so that's one thing I will be doing.
